I saw this today on the Rawr website, it made me laugh...
The current gemming system is unintuitive, hard to use, and cluttered. We know. We're revamping the gemming system for the next version of Rawr. No further reports of how much it sucks are required.
That's just funny. And one of the primary reason why I don't use Rawr. The UI (not just the gemming) is so clunky and unintuitive it makes it almost worthless.
